Benefits of technology

[0008]The present disclosure provides a portable electric device capable of sharing multimedia contents by wireless without time delay or image deterioration, and a display mirroring method of the portable electric device.
[0010]The present disclosure also provides a portable electric device that can perform bidirectional display mirroring and data sharing, and a display mirroring method of the portable electric device.

Problems solved by technology

If such limiting factors as data transmission rate, bandwidth, and power consumption are not sufficiently considered, there may be a time delay between user devices during wireless data sharing or display mirroring.
In addition, due to the resolution difference between user devices, the quality of a screen shared or mirrored by wireless connection may be decreased.
